Acrylic Interlock Knit Fabric for Activewear — Specification, Uses and Sourcing Notes
Acrylic Interlock Knit Fabric for Activewear: Specification, Uses and Sourcing Notes
Acrylic Interlock Knit Fabric is the version buyers specify for activewear when the base material is fixed by performance rather than by price. This entry sets out what the material actually changes, which specification to write into the tech pack, and where the cost sits — the three questions that decide whether the item passes bulk approval.
What it is
Acrylic gives interlock knit fabric its durability under wash and abrasion. In practice that means the fabric behaves differently in cutting, in finishing and in wear: shrinkage allowance has to be built into the spec. Buyers who specify the material up front avoid the most common failure — an item that looks right on the sample card and behaves differently in bulk.

How to specify it
